Rb20 With Gt3071r

[RB ONEVIA]

ok im getting said turbo and i want to know if anyone can tell me the following:

a) are you using the .63 or .84 exhaust housing? im thinking .84 too big.

B) what engine mods you have?

c) what rpm full boost is at?

d) what boost you are running?

e) rwkw?

slowly making my way through this thread but no luck as yet http://www.skylinesaustralia.com/forums/Rb...no-t103095.html

Cheers Adam

Would be good to see a graph of this. I'm thinking .84 is too big too. RB25 gets decent boost at 3500 with a .63 Maybe a little more.

Got a 0.63 on mine (RB25). Pushing about 5 psi by 2000 rpm, full boost (18psi) by about 3100 rpm. Great response, but has a issue with boost creep; the housing seems to just be too small on these things. Having said that, you may have more luck on an RB20.

I'd put a picture up, but the uploads arent working

LOL, so many people ask questions etc about this sort of setup then we never see the results

It cant be that much different then a TD06 setup, so will be laggy but have decent enough response and power from 4,000rpm on up. But since noone canb give you real life results then you will end up being a guinea pig to some extent.

So 0.63, its easier to live with too small and choked up top, then laggy SOB that never makes the power it should. You can also port/extrude hone the smaller out to suit the engine.

wouldnt mind seeing some results either
